Fukushima: de nouvelles images inquiétantes

« Il y a des zones que nous n’avons pas pu voir » à l’intérieur de ce réacteur, mais les dégâts sont probablement « étendus sur beaucoup d’endroits », a déclaré un responsable de Tepco lors d’un point de presse.

Fukushima: de nouvelles images montrent les dégâts dans un réacteur

La vidéo a notamment montré des murs en béton ébréchés exhibant leur armature en acier et des débris empilés sur un demi-mètre de hauteur.

Ces images illustrent une nouvelle fois la tâche colossale que représente la décontamination et le démantèlement de Fukushima Daiichi, qui doit encore durer des décennies.

Dans les réacteurs 1 à 3, le combustible et d’autres matériaux ont fondu lors de la catastrophe puis se sont solidifiés en débris hautement radioactifs.

L’extraction de ces déchets ne pourra ainsi être réalisée que par des robots pilotés à distance. Mais le démarrage de cette opération extrêmement complexe a pris du retard, du fait de la pandémie et de difficultés techniques.

« A cause des niveaux de radiation élevés au sein des réacteurs, je comprends que les robots utilisant des semi-conducteurs ne fonctionnent pas aussi bien » que prévu, a déclaré lundi lors d’une conférence de presse le gouverneur du département de Fukushima, Masao Uchibori.

Le gouverneur a demandé à Tepco de mener de nouveaux tests de résistance anti-sismique de la centrale, alors que ses administrés s’inquiètent d’une aggravation de la situation sur le site si une nouvelle catastrophe naturelle de grande ampleur se produisait.
